Assignment Operators in C | Shorthand operators in C
Assignment/shorthand operators are used to update the value of a variable in an easy way. There are various assignment operators provided by C language.
- =
- +=
- -=
- *=
- /=
- %=
- &=
- |=
- ^=
- <<=
- >>=
Operator |
Description |
| = | It is used to assign some value to a variable.
Example: A=10 |
| += | It is used to increment the value of a numeric variable by adding some value to the existing value.
Example: A=10 |
| -= | It is used to decrement the existing value of a numeric variable by subtracting some value from the existing value.
Example: A=10 |
| *= | It is used to multiply existing value of a numeric variable by another value and then store the result in it.
Example: A=10 |
| /= | It is used to divide the existing value of a numeric variable by another value and then store the result in
Example: A=10 |
| %= | It is used to divide the existing value of a numeric variable by another value and then storing the remainder in it.
Example: A=10 |
| &= | It is used to apply bitwise AND operator on existing value of a numeric variable by another value and then storing the result in it.
Example: A=10 |
| |= | It is used to apply bitwise OR operator on existing value of a numeric variable by another value and then storing the result in it.
Example: A=10 |
| ^= | It is used to apply bitwise XOR operator on existing value of a numeric variable by another value and then storing the result in it.
Example: A=10 |
| <<= | It is used to apply Bitwise LEFT SHIFT operator on existing value of a numeric variable by another value and then storing the result in it.
Example: A=10 |
| >>= | It is used to apply Bitwise RIGHT SHIFT operator on existing value of a numeric variable by another value and then storing the result in it.
Example: A=10 |
Example 1
Program to demonstrate shorthand operators in C |
#include<stdio.h>
int main()
{
int a=20;
|
a+=4;
printf("\na=%d",a); /*a=24*/
|
a-=13;
printf("\na=%d",a); /*a=11*/
|
a*=6;
printf("\na=%d",a); /*a=66*/
|
a/=5;
printf("\na=%d",a); /*a=13*/
|
a%=5;
printf("\na=%d",a); /*a=3*/
|
return(0);
}
|
Example 2
Program to demonstrate the use of shorthand operators in C. |
#include<stdio.h>
int main()
{
int a=10;
|
a&=7;
printf("\na=%d",a); /*a=2*/
|
a=10
a|=7;
printf("\na=%d",a); /*a=15*/
|
a=10
a^=7;
printf("\na=%d",a); /*a=13*/
|
a=10
a<<=1;
printf("\na=%d",a); /*a=20*/
|
a=10
a>>=1;
printf("\na=%d",a); /*a=5*/
|
return(0); } |
